2.4.1 UX5000 Central Processing Unit (CCPU) Blade (Figure 2-4 - Figure 2-5) - P/N 0911001
The CCPU controls all the functions and operations of the UX5000 system using the system software loaded
into the CCPU memory. The system software can be upgraded as new software becomes available.
One CCPU blade must be installed in the CCPU slot in the Controlling chassis. In a networked system using
CygniLink and an IP connection, a second CCPU can be used for a CCPU Fail Over feature (primary/
secondary CPUs) as a backup in case of a hardware or power failure. (The CCPUs must be programmed for
primary/secondary operation.)
The CCPU functions are:
● Music on Hold tone Circuit, External Source Control circuit
● Voice Mail Daughter Board Interface Circuit
● System Program and System Data Storing Memory Circuit
● USB Interface Circuit
● Ethernet Interface Circuit
● EXIFU-A1 Interface Circuit
● Main Processing 32-Bit CPU Circuit (MPC8248 @ 266 MHz)
● Time Switch, Optional Blade Control Circuit
● Backboard Interface Circuit (TDM and IP Backbone with TDM backplane and IP on front)
2.4.1.1 The CCPU (P/N 0911001) provides:
● 200 trunk ports maximum (with MEMDB installed and licensed expansion)
● 512 extension ports maximum (with MEMDB installed and licensed expansion)
- 512 ports digital/IP extensions maximum
- 320 analog ports maximum
● 256 virtual extensions
● Connection for 32/64/128 VoIP Daughter Board
● Connection for Voice Mail Daughter Board
● Connection for Expanded Memory (MEMDB-A1)
● Supports TAPI 1.x
● 1 Green Status LED and 4 Red Status LEDs
During normal operation, the “RUN” LED will be flashing and the remaining LEDs will
be off.
● Tone Generator
● Tone Processing DSP
